This invention relates to a new and improved stove construction, andmore particularly to a construction of liquid fuel types of stoves offorms which are collapsible, in

order to render them readily portable. Stoves of this character, ingeneral, comprise a housing, one or more burners, a fuel tank andconnecting piping between the fuel tank and burners. It is customary tohave such a connection between the fuel tank and burner assembly as topermit the tank to be placed within the housing for purposes oftransport and to be placed outside of thehousing when in use. This isdesirable since it permits a wall of the housing to be between the tankof inflammable fuel and the flame from the burners. In usual types ofconstruction this result is obtained by disconnecting the tank from theburner assembly when placing the tank in the housing. This isundesirable, since it makes the tank a disconnected element which maybecome displaced or lost and also because it involves a loose connectionin the fuel piping which may leak or become disconnected during the useof the stove.

It is an object of the present invention to provide a stove constructionin which the tank is permanently connected to the burner assembly, andin which the tank may be moved 30 into and out of the housing.

' It is a further object to provide a construction of this character, inwhich the burner assembly is permanently connected to the housing.

It isalso an object to provide a construction in which the connectionbetween the burner assembly and housing is adapted to permitdisplacement of the assembly relative to the housing such as to enablethe tank to be lifted over a wall of the housing in moving it from oneposition to another.

Itis an additional object to provide a construction of this character,which is composed of but few and simple parts and adapted for rapidcommercial production.

Other and further objects will appear as the description proceeds;

I have illustrated certain preferred embodiments of my invention in theaccompanying drawings, in which 7 V Figure 1 is an elevation of one formof construction, certain portions being broken away;

Figure 2is a plan view taken on the line Figure 3 is a view similar toFigure 1, but showing the parts in the traveling position;

Flgure 4 is a section taken on the line 4.4 of Figure 2;

Figure 5 is a fragmentary view showing the fuel valve construction, and

Figure 6 is a view similar to Figure 1, but showing a modified formofconstruction.

Referring first to'the form of construction shown'ln Figures 1 to 5, theburner assembly 11 is carried within the housing 12. This houslng 12 isprovidedwitha hinged lid 13, with wind breaks 14 hingedly connected tothe lid and with the pivoted supporting legs .15; The housing is alsoprovided with the grate 16 which is .pivotally connected to the housingand which rests on'the flange members 17 and 18. I p

The fuel pipe 19 is connected at one end to the needle valve 20, whichlatter is secured to the 'fuel tank 21. The pipe 19 is alsosecured tothe burners 22 and 23 by means of the clips 24: and 25 and its end 26islocated so as to discharge into the lower portion of the burnerassembly 11. 'The burner assembly is provided with the connecting pin27, to the ends of which are secured the links 28. The links 28 arepivotally connected to the links 29, the opposite ends of which aresecured to the'member 80, which latter is secured to the bottom of thehousing 12.

The tank 21 has secured thereto the hooks 31, the upper ends of whichare adapted to engage an edge of the housing whenthe stove is inoperating position. As shown in detail in Figure 5, the needle valve isprovided with the handle 32 by which the flow of fuel from the tank 21to the pipe 19 may be controlled. The intake pipe 33 of the valveextends down close to the bottom of the tank 21. As shown in Figures 2and 6, the tank 21 is provided with a valve fitting 34 by means ofwhich'fuel may be placed in the tank. Also, this fitting permits airunder pressure to be forced into the tank above the fuel, so as to forcethe fuel to pass up through the pipe 33 and pass the valve 20 andthrough the pipe 19 to theburners. 7 t The form of construction shown inFigure 6 differs from that previously described only in the means ofconnection between the'burner assembly 11 and housing 12 and in theconstruction and the connection of the fuel pipe.

In this form of construction the burner assembly 11 has connectedthereto a pair of links 35, the opposite ends of which are connectedto-"the member 36, the latter member being secured to the bottom of thehousing. The pipe 37 connects the tank and burner assembly'and is heldupon the'top ofburners 22 and 23 by clips 38 and 39. These clips 38 and39 somewhat loosely engagethe pipe 37 so that it may be movedlongitudinally relative to the burners.

The position of the tank 21 when traveling is indicated in broken linesat 21". The position of the inner end of gipetl'i when traveling isindicated at 37 by roken lines. The

burner assembly and link are in the same p0 sition when traveling andwhen the stove is in use. They are moved from this posit on only whenmoving the tank and connectlng piping fr m working to traveling positionand vice versa. 1

In moving the parts of the form of construction shown in Figures 1 to 5from the traveling position shown in Figure 3 to the working positionshown in igure '1, it is merely necessary to lift the burner and tankassembly until thetank clears the upper edge of the side of the housing.to move it laterally until the hook members 3l-are located approximatelyabovethe edge of the housing and to lower it until the hooks engage thehousing edge. The bottom of the burner assembly'will then rest againstthe member 30 inside of the housing, as clearly shown in Figure 1. Torestore the parts totraveling position, the burner and tank assembly is.lifted, moved to the right and lovered to the position shown in Figure 3These movements are limited and guided by the links 28 and 29 whichpermanently secure the parts together. It will be understood that duringthese movements ofthe burner and tank assembly it will be necessary toswing thelid or cover 13, the wind breaks 14 and the grate 1611p; out ofthe way. of the movement.

In moving the parts ofthe form of con struction shown in Figure 6 fromthe traveling position shown in broken lines to the operating positionshowing full lines, the left or tank end of the assembly is s zvungupwardly, so that the tank may clear the edge of the housing 12 andrthetank is moved to the left away from the burner assembly until it may belowered to bring the hooks 31 into engagement with the upper edge of thehousing wall. This lateral movement of the tank is permitted by thesliding connection between the pipe 37 and the clips 38 and 39. Inrestoring the parts to traveling position, the tank end is swung up.until the tank may be moved to the right and then lowered into thehousing. During this movement, the pipe '37 slides to the right relativeto the .clips 38 and 39 and the burners 22 and 23.

It will be understood that in the use of the stove the tank 21is filledwith gasoline or similar fuel through the filling opening closed by cap34;. Air under pressure is then forced into the tank above the fuel. Tostart up the stove the Valve 20is opened by means of handle 32, andthe'air pressure forces the fuel past the valve and through the pipe 19.It drips into the heating pan 40, and, when a small amount hasaccumulated'thcrein, it is ignited and serves to heat part of the pipe19 and the burner 23. The gas in the pipe is thus vaporized by heat andpasses out of the pipe 19 into the burner assembly in the form of vaporand then up through the assembly to the burner 23 where it is ignited.During the use of the stove the heat from the burners vaporizes the fuelin the pipe passing over them and none of the fuel enters the pan 10.The burner- 22 is controlled by valve 41. t

'. The supply pipe 33 extends nearly to the bottom of the tank 21 andtherefore prac:

tically all of the fuel in the tank can be forced out by the air aboveit. The fuel leads from the pipe 19 at a level below that of the normalfuel level in the tank and the siphon action assists the flow of thefuel. The fuel'enters the burner assembly from below and rises to theburners and its movement is assisted by the normal upward movement ofthe heated gases.
